Permit Requirements in Maryland
The Maryland Building Performance Standards adopt statewide minimum building, residential, energy, accessibility, and related construction codes. Baltimore City and each county administer permits locally and may adopt local amendments. Maryland is not a single statewide permit portal: the parcel's independent city, county, or incorporated municipality determines the filing path.
